Class 180 Fully Insulated (Zero Defect) Solderable Round Enameled Copper Wire

Rvyuan FIW wire can be a substitute for TIW wire when they are applied to switching power transformers. As there are a huge range of selection of overall diameters for FIW wire, costs can be reduced. Meanwhile, it has better windability and solderability compared to TIW wire.

1.High temperature rating, G180;
2.High dielectric breakdown voltage min. 15KV
6000Vrms,1min;
3.High dielectric strength
(No need to peel off the film)
4.Solderable: 390℃,2s
5.Resistance to softening, 250℃, no breakdown, 2 minutes
Over Air Reflow (peak temperature at 260°C), the enamel doesn't crack
6.Can be customized to produce natural color (N) / red (R) / green (G) /
Blue(B)/Purple(V)/Brown(BR)/Yellow(Y)
7.Excellent winding performance is suitable for high-speed automatic winding machine to improve efficiency;
8. The size is small, minimum of 0.11mm. Extrusion wire is not accessible;
9. The price of FIW wire is lower and about half cheaper than three-layer insulated wire of the same specification.
